The correct sequence for a reflex arc involves the receptor detecting a stimulus and sending a signal through the sensory neuron to the spinal cord, where it may briefly communicate with the brain if needed, then transferring via a motor neuron to the effector to elicit a response. This allows quick reactions without prolonged processing in the brain.
